A client is receiving isoniazid after being diagnosed with tuberculosis. Which information should the nurse include in the client's teaching plan?
Take vitamin B6 daily to prevent peripheral neuropathy.
Your urine and tears may turn orange.
Arrange for a hearing exam to monitor for hearing loss.
Wear sunscreen to prevent photosensitivity reactions.
The Correct Answer is A
Choice A reason:
Isoniazid, an antitubercular medication, can cause peripheral neuropathy, a form of nerve damage characterized by numbness, tingling, or pain, particularly in the hands and feet. This side effect is due to the drug's interference with the normal metabolism of vitamin B6 (pyridoxine). Supplementation with vitamin B6 is recommended to prevent this complication. The normal daily recommended intake for vitamin B6 in adults ranges from 1.3 to 1.7 mg.
Choice B reason:
While it is true that isoniazid can cause discoloration of bodily fluids, turning urine and tears orange, this is not a harmful side effect and does not require intervention. It is, however, important to inform the client of this possibility to prevent alarm.
Choice C reason:
There is no evidence to suggest that routine hearing exams are necessary for clients taking isoniazid unless they have pre-existing hearing conditions or are taking other medications known to affect hearing. Therefore, this is not a standard part of the teaching plan for clients on isoniazid.
Choice D reason:
Photosensitivity reactions are not commonly associated with isoniazid use. While wearing sunscreen is generally good advice for skin protection, it is not specifically related to the administration of isoniazid and thus would not be the primary information to include in the teaching plan.

Correct Answer is B
Explanation
Choice A Reason:
Using accessory muscles while breathing is a sign of respiratory distress and indicates that the client is working harder to breathe. This is not a desired outcome of treatment and suggests that the asthma exacerbation is not under control.
Choice B Reason:
The ability to answer questions in full sentences suggests that the client's airway is not severely obstructed, which is a positive sign of effective asthma treatment. When asthma is well-controlled, individuals should not experience significant shortness of breath that limits their ability to speak.
Choice C Reason:
Diminished breath sounds can be a sign of severe airway obstruction and are not indicative of effective asthma treatment. Ideally, lung auscultation should reveal clear breath sounds without wheezing, indicating good air movement throughout the lungs.
Choice D Reason:
Restlessness and anxiety can be symptoms of hypoxia, a condition where the body or a region of the body is deprived of adequate oxygen supply. This is not a sign of effective asthma treatment and may indicate that the client's asthma is not well-managed.
Correct Answer is D
Explanation
Choice A Reason
While maintaining a stable blood pressure is important for a client with hypertension, furosemide is primarily a diuretic, and its therapeutic effect is to reduce fluid overload, not directly to stabilize blood pressure. Therefore, this finding alone does not best indicate the therapeutic effect of furosemide.
Choice B Reason
Clear lungs upon auscultation suggest an improvement in pulmonary edema, which can be associated with fluid overload in conditions such as heart failure. However, for a client with peripheral edema, the primary therapeutic goal of furosemide is to reduce the excess fluid in the extremities, not just the lungs.
Choice C Reason
A decrease in serum potassium is a known side effect of furosemide due to its action on the kidneys, leading to increased excretion of potassium. While it's important to monitor for hypokalemia, a decrease in potassium does not directly indicate the therapeutic effect of reducing edema.
Choice D Reason
An increase in urine output from 30 mL per hour to 100 mL per hour is a direct indication that furosemide is achieving its therapeutic effect. Furosemide is a loop diuretic that increases urine production to help the body eliminate excess fluid, thereby reducing edema associated with conditions like hypertension.
